WebDec 26, 2024 · Level Order Binary Tree Traversal Using Queue. For each node, first, the node is visited and then it’s child nodes are put in a FIFO queue. Then again the first node is popped out and then it’s child nodes … WebExample 1: Input: 3 / \ 1 2 Output: 1 Explanation: The sum of left subtree and right subtree is 1 + 2 = 3, which is the value of the root node. Therefore,the given binary tree is a sum tree. Example 2: Input: 10 / \ 20 30 / \ 10 10 Output: 0 Explanation: The given tree is not a sum tree. For the root node, sum of elements in left subtree is 40 ...

WebFeb 16, 2024 · Approach: From the diagram it can be seen that every element is either printed diagonally upward or diagonally downward. Start from the index (0,0) and print the elements diagonally upward then change the direction, change the column and print diagonally downwards. This cycle continues until the last element is reached. Algorithm: WebJan 17, 2024 · Given a binary tree, delete a node from it by making sure that the tree shrinks from the bottom (i.e. the deleted node is replaced by the bottom-most and rightmost node). This is different from BST deletion. Here we do not have any order among elements, so we replace them with the last element.
WebMar 8, 2024 · Video. Given a Binary Tree, the task is to print the elements in the Vertical Zig-Zag traversal order. Vertical Zig-Zag traversal of a tree is defined as: Print the elements of the first level in the order from right to left, if there are no elements left then skip to the next level. Print the elements of the last level in the order from left ... WebApr 6, 2024 · Method 2 uses the following rules to get the sum directly. 1) If the node is a leaf node then the sum of the subtree rooted with this node is equal to the value of this node. 2) If the node is not a leaf node then the sum of the subtree rooted with this node is twice the value of this node (Assuming that the tree rooted with this node is SumTree).
WebApr 9, 2024 · Approach: For Principal Diagonal elements: Run a for a loop until n, where n is the number of columns, and print array [i] [i] where i is the index variable. For Secondary Diagonal elements: Run a for a loop until n, where n is the number of columns and print array [i] [k] where i is the index variable and k = array_length – 1. WebJan 27, 2024 · Check if a binary tree is subtree of another binary tree. [Method 2 ] ( Efficient solution ) An Efficient solution based on tree serialization and hashing. The idea is to serialize subtrees as strings and store the strings in hash table. Once we find a serialized tree (which is not a leaf) already existing in hash-table, we return true.
